Seasons play an important role in the performance of breeder chickens, but lack of adequate records on its specific effects in specific seasons could influence the efforts of breeders to improve on local ecotypes of chicken for standardization into breeds. This is why Nigeria still depends mainly on imported breeds of chicken for commercial production of chicken. In this study, the influence of Early Wet (EW), Late Wet (LW) and Early Dry (ED) and Late Dry (LD) seasons on reproductive parameters of Bovan Nera (BN) and Isa Brown (IB) parent-stock chickens were studied in the humid South-West Nigeria. Ten-year data on both genotypes were obtained from Ajanla Farms Hatchery Ibadan and analysed for Eggs Set (ES), Egg Fertility (EF), Egg Hatchability (EH), Pullet Day-old Chicks (PDC) and Hatching Rejects (HR) to study the effect of seasons on these parameters. ANOVA (p<0.05) showed that seasons have significant influence on EF, EH and HR in BN; and ES, EH and HR in IB. Late wet season gave the best results on reproduction thus making it potentially the most favorable season for hatching activities in both genotypes, and therefore may signal good fortune in commercial chicks production enterprises of breeder chickens in hot humid regions.
